Wrist Ligaments Anatomy

The wrist links the hand to the arm. The most important intrinsic ligaments are the scapholunate interosseous ligament and lunotriquetral interosseous ligament.

The carpal bones are organized into 2 groups a proximal row and a distal row.

Wrist ligaments anatomy. Anatomy of the hand and wrist. Bones muscles tendons nerves. As noted eight carpal bones the distal radius and ulnar.

The intrinsic and extrinsic wrist ligaments play a vital role in the stability of the wrist joint. Intrinsic ligaments only attach to carpal bones scapholunate ligament. The ligaments of the wrist include extrinsic ligaments bridge carpal bones to the radius or metacarpals.

A small pad of cartilage similar to the meniscus of the kneethat cushions. Intrinsic ligaments originate and insert on carpal bones. Extrinsic ligaments of wrist.

There are numerous ligaments but included below are the most clinically significant. Additionally they help in the flexing and movement of the wrist hand and fingers. The wrist contains a network of ligaments including.

8 carpal bones the distal radius and ulnar and the bases of the 5 metacarpals. A cord shaped ligament that attaches the ulnar styloid on the. An extension at the bottom of the ulna where the wrists pinky side collateral ligament.

The capsule is double layered. Anatomy of wrist bones joints muscles and ligaments bones of the wrist. Ligaments of the wrist palmar view.

Include volar and dorsal ligaments. 2 the wrist joint or radiocarpal joint the joint between the radius and the carpus and 3 the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones thus referred to as wrist joints. The wrist is a complex mechanical system of 8 small bones known as the carpal bones.

The carpal bones are arranged in 2 interrelated rows. It passes from the radius to both rows of carpal bones. Palmar radiocarpal it is found on the palmar anterior side of the hand.

Ligaments and tendons play a large part in hand and wrist anatomy as they are the connectors and support system for the intricate system of bones. There are four ligaments of note in the wrist joint one for each side of the joint. Intrinsic ligaments that connect the wrist bones to each other.

The wrist has multiple ligaments that provide stability. Ligaments of the wrist posterior dorsal view. The tendons of the wrist are the connecting fibers that attach muscle to bone.

Extrinsic ligaments attach to structures aside from the carpus volar. Its function apart from increasing stability is to ensure that the hand follows the forearm during supination. The anatomic linkage between the distal forearm and the hand is composed of 15 bones.

Wrist ligaments are best assessed with dedicated wrist mri. Extrinsic ligaments that connect the wrist bones to the long bones of the forearm and the bones. One row connects with the ends of the bones in the forearm radius and ulna.

In human anatomy the wrist is variously defined as 1 the carpus or carpal bones the complex of eight bones forming the proximal skeletal segment of the hand.
